oil, so as to reduce the volume of drained oil. Turn adjusting bolt clockwise to reduce discharge, anticlockwise to increase discharge. Therefore, changing the position of bolt enable discharge approach academic volume and reach the requirements on measurement transducer of national appraisal regulations. As two regulative bolts access to adjusting piston, the adjusting discharge in a circulation per bolt can be calculated in the following formula: △V = 1/2πd12 nt fuel dispenser (2--4 ) △V ── adjusting value in per circulation; D1 ── diameter of regulative piston; n ── turning number of adjusting bolt; t ── screw- pitch of adjusting bolt. There is another metal piston measurement transducer in current market. See the Diagram 2-19. Regulative piston is singularly installed in piston rather than connect with rod in this model. Its adjusting value in terms of per adjusting bolt is: △V = 1/4πd2 nt (2 fuel dispenser --5 ) Common failure and Troubleshooting Metal piston measurement transducer has the two common failures --- accuracy decline and mechanical trouble. Measure accuracy beyond scope The allowed measurement accuracy of fuel dispenser is ±0.3 %, repeated tolerance no more than 0.15 % according to the stipulation of JJG443-98 Fuel dispenser. The maximum allowed tolerance of min. measured valve don’t exceed ±0.5 %，its repeated tolerance no more than 0.25 %. The ratio of maximum flow (Q max.) to minimum flow (Q min.) is 10 to 1. as fuel dispenser leave factory. The ratio should not be less than 5: 1 in inspecting at operation locale. All of exceeded tolerance is regarded as beyond measurement accuracy. There are many elements and reasons resulting in measurement accuracy beyond scope, including unstable hydraulic system (extensive pressure fluctuation), electric system failure, thick colloid in frictional interface, measurement transducer abrasion, etc. The last two reasons will mainly be introduced in this article.

Shop will be allowed to operate as an independent unit, which sounds sensible. But will L Oréal really be able to resist slipping its ethically challenged anti-wrinkle cream onto the shelves next to the bracing and “naturally inspired�body scrubs offered by the Body Shop? © 2006 .  About sponsorship Photography Down with the shutters Mar 23rd 2006 From The Economist print edition Competition in digital phot fuel dispenser ography takes another turn AT THE end of this month, Konica Minolta will make its last camera. After more than 100 years the Japanese company, which is also the world s third-largest producer of photo film, will begin a complete withdrawal from the photography business. In future it will stick to making photocopiers, printers and medical devices. The company is the latest victim of the wholesale change brought to an entire industry by the digital camera. Other fuel dispenser big names in the photography business have suffered badly in the digital age. Kodak, an American group which lost almost $1.4 billion last year, is only midway through a restructuring. Like Japan s Fuji Photo Film, which after Kodak is the world s second-largest film supplier, it has seen revenues from its traditional business collapse much faster than was expected. In little more than a decade, sales of digital cameras have soared; they have now almost completely replaced film cameras. But now even the digital camera business is maturing. After growing by 670% in 2000-05, unit sales of digital cameras are slowing. Worldwide sales are expected to rise to just over 100m a year by 2009, an increase of only 26% (see chart). At the same time, prices are tumbling. Digital cameras have rapidly become a “mature�consumer product. Persuading people to trade up to more expensive digital cameras is one obvious response. An intense battle is looming between Canon and Sony, the two market leaders. Last year Canon captured about 18% of the worldwid fuel dispenser
